mem limit weird bug str parsing

[robomotic]

Hi there,
I am following the documentation but getting the error:

    traitlets.traitlets.TraitError: The 'mem_limit' trait of a ResourceUseDisplay instance expected an int or a callable, not the str '16341940'.

The commandline shows that is indeed an integer unquoted, so I am not sure what is happening.

Thanks @robomotic for reporting.

It sounds similar to jupyter-server/jupyter-resource-usage#86, and would probably have to be fixed in the jupyter-resource-usage repo.

Oh what a PITA, well I will just wait for the fix. Thanks for letting me know.

Closing as jupyterlab-system-monitor has now been integrated in jupyter-resource-usage: jupyter-server/jupyter-resource-usage#191

Let's continue in jupyter-server/jupyter-resource-usage#86.

Thanks!
